SIGNAL ARRESTERS (3-WIRE SIGNAL)

SIGNAL ARRESTER
DA -■ UseDA series are indoor installation type arresters that canabsorb voltage of induced lightning surge caused on a signal
line by lightning discharge, thus protects instrument.

■ Features
1. Besides small plug-in structure, the device has a structure that line does not open even if
main body is pulled out of terminal block. This feature makes the device superior inconservativeness.
2. Absorbs only surge without influencing measurement signals.

■ Features
1. Besides small plug-in structure, the device has a structure that line does not open even if
main body is pulled out of terminal block. This feature makes the device superior inconservativeness.
2. Both DA – 1

AR SERIESPOWER ARRESTER
AR-100, AR-200■ Use
This device is an arrester that absorbs lightning surge penetrating from acommercial power line of instrumentation machinery. There are two kinds ofthem by power source voltage, AR-100 (for AC100/110V) and AR-200 (forAC200/220V). The device is designed to allow power source electricity of 50/60Hz
to pass through it freely. A fuse (2A) is installed in power source circuit to protect
the power source in case that a discharge element was destroyed by a lightning
surge exceeding tolerance.
Plug in structure that makes maintenance/check easy. There is a power source
indication lamp as well.
To use this device effectively, read the following items before handling it.

Munsell N1.5 (black)A discharge element in the device may initiate a discharge and causes defective withstand voltageof the device if a withstand voltage test (MAX. 2,000V between electric circuit and earth) of the panel
having the device installed in was carried out. So, when implementing a withstand voltage test,
remove all earth wires jointed to terminals. (power source line should be cut out if the device waspulled out, and the voltage test could be considered as not being carried out.)* Make sure to reconnect the detached earth wire as before after withstand voltage test.
